I'm about to move to RISC.  I have read about the CFINT governor.  If my
daily backup (library *ALLUSR) runs interactively in a restricted
system, will this governor kick in and not allow the backup to proceed
as fast as in batch?

4 days a week (Mon-Thu), the operator inserts the tape into the drive
and takes the backup option.  This backup is then submitted and then
runs at 4am in batch.  On Friday evening, however, it runs immediately
(ain't nobody here on Saturday).  I used to do it interactively.  I was
afraid that this would kill performance under RISC, so I batched it. 
The interactive job (which is in subsystem QCTL) stays active and keeps
the operator advised of the status.  The problem is the interactive job
user's message queue object does not get saved from QUSRSYS since it is
allocated to the interactive job.  If I go back to running this
interactively on Fridays, this problem would go away, but what about
that rascal CFINT job kicking in?

The opinions expressed are my own and not necessarily 
the opinion of my company.  Unless I say so.
